To aZl whom it may concern:

Be it known thatd, HUGH WM. GRAEML'a citizen of the United States, residing at Louisville, in thccounty of Jefferson and State of Kentuchy,have invented certain new and useful improvements in Siphons; and i do here by declare the following to be a full, clear, and exact description of the i ventiomsuch as will enable others skilled int part to which it ap pertains to make and use. the same.

My invention relates tit water-distributing systems inwhich the water is conveyed from a river, canal, ditch, po'ol, orother reservoir or source of supply over some intervening bank, wall, or other obstruction to the point of distribution by means of a siphon. Its ob jects are toprovide efficient means for opening andolosing the siphon ,starting, stopping, and regulating the flow, and converting the power of the moving column of water into a convenient and useful means of driving machinery.

To this end. my invention consists in the improved construction, arrangement, and combination of parts hereinafter described and specifically pointed out in the claims.

ln'thc drawings similar referencedetters in dicate similar parts in the several figures illustrating my invention.

Figure l is a broken side elevation of a siphon constructed according to myinvcntion.

Fig. 2 is an enlarged detailview in section of the lower end of the short or inlet leg of Fig.

1. .Fig'". 3 is a side view of the short leg of a siphon, showing in section modified form of an inlet-gate. Fig. l-is a side View in elevation of a modified form of the long leg of Fig. l,showing a double turbine. Fig. 5 is a sec- ,ondflmogliiied form of the long log of Fig. 1,

showing its division into two branches, with a turbine in one of them only.

In the figures, S is the siphon, of metal or other suitable material, which inv practice willconform in shape and length to the size and shape of the bank or other obstruction over which the water is to be carried.

E is a short pipe projecting upwardly from the highest portion of the-siphon, into the top of which is let the tubular nipple u, the passage-way through it being opened and closed by a suitable valve (not shown) operated by the thurnbscrew t. The functions of this do vice arc to admit air under pressure to the interior of'the siphon for the purpose of expelling the water when desirable, with a view to the prevention of freezing, to serve as aconduit for the air in the siphon when it is desirable to exhaust it, with a view to causing the water to rise in the siphon to its highest point, and to adniit water to the interior of the siphon when it is desirable to fill it in that manner, in which case a vent (not shown): must be provided for the interior air to escape. Lin-either case the funnel or exhaust or force-purhp may be attached to nipple n, which is screw-threaded for such purpose. Cap .fits snugly, over pipe E, both to protect it from the weatlier and to aid in keeping it air tight. On the top section or crown of siphon f is'the cohort 'viaiv'e V, or any suitable construction, its function being to instantaneously stop or start the flow of the water when the siphon is full, in the former case the Water being held in suspension until the operator is ready to resume operations, when a more turn of the valve will again start the flow. Valve V may also serve as a' convenient regulator of the amount of Water passing through the siphon during any given period.

I is the shorter or inlet legof the siphon, its lower end being usually bent, as indicated, and Gis a sliding gate or valve adapted to close it when desired. Gate ,Gr falls by gravity,

aided also by spring 5 in casing 70, and is raised by chain '1", passing over rollers p p, and attached to rod r. Theupper end of rod 9" passes into a tubular extension 2' of pipe I, where it engages with screw-threaded operating-nut t, by the turning of which it-is raised or lowered, as desired. A modified form of inlet gate or valve is G, (shown in Fig. 3,) which is hinged to the outer end of pipe I and is raised and lowered by rod w, slidingly scoured to the upper part of pipe I in any suitable manner. Rod 10 is attached to the outer end of latch Z, which is pivotally-secured to gate G. To the outer face of G is secured guide-rod n, which passes through a slot in sliding rod m, which is pivotally attached to the outer edge of latch Z, the function of the device being to latch gate G securely to pipe I when its mouth is to be closed and to unlatch and raise it upward when it is tobe 2 tenets of the gate and latching device when raised are illustrated by dotted lines.

Over gates G and G will he usually placed a cage K ofany suitable construction (shown 'insectional elevation) for the purpose of keeping ice, driftwood, and

other such articles out of the siphon.

O is the longer or outlet leg of the siphon,

the discharge of Water from its lower end being regulated by pivoted valvec, opera-ted by rod 7', attached thereto, whose upper end passes into tubular extension 0, where it engages with screw-threaded nut t and is covered by cap 0. Pipe 0 may be arranged to discharge into any suitable reservoir, ditch, or conduit, or be immersed in a stream of water, as indicated in Figs. 1 and 4.

T is a turbine, of any suitable construction, located in the crown of the siphon and adapted to be actuated by the water flowing through it. The turbine may be placed at any part of siphon S, provided it is above the level of the water in the reservoir, as in Fig. 4, for example, where T is a double turbine actuating pulleys P and gears P, and into it pipe 0 discharges, the waste water passing through its branches 1) and I). .by shafting B power may be communicated to any desired point.

In Fig. 5 the turbine is one of these branches, and a hinged valve 2) is so arranged as to divert the water into either branch, as desired, tothe end that the turbine may be stopped Without interfering with the flow of the water.

Having thus fully described my invention,

shown as located in what I claim, and desire to secureby Letters" Patent, is? r 1. A siphon in'combination with a turbine,

said turbine being located above the level of the water in the reservoir and adapted to be actuated by the liquid flowing through the siphon.

2. A siphon in combination with a turbine, said turbine being located in the crown of the siphon and adapted to be actuated by the liquid flowing through the siphon.

A siphon in combination with an inlet and an outlet valve or gate located respectively at the extremities of the short and long legs of the siphon and adapted to be opened and closed by rods passing upward inside the legs and through the walls of the siphon.

1-. A siphon in combination with a vertically-sliding' inlet valve or gate and a chain passing upward inside the shorter leg of the siphon and through its wall and adapted to lift the gate and to let it fall.

5. A siphon in combination with an outletvalve located at the extremity of the longer leg of the siphon and adapted to be opened and closed the longer siphon. I

In testimony whereof I my in presence of two witnesses.
